DETAILED DESCRIPTION

In order to make objects, technical solutions and advantages of the embodiments of the present disclosure apparent, the technical solutions of the embodiments will be described in a clearly and fully understandable way in connection with the drawings related to the embodiments of the disclosure. Apparently, the described embodiments are just a part but not all of the embodiments of the present disclosure. Based on the embodiments of the present disclosure, those skilled in the art can obtain other embodiment(s), without any inventive work, which should be within the scope of the present disclosure.

Referring to FIG. 1 , FIG. 1 is an example diagram of video capturing in the prior art. In the prior art, the salient object segmentation for a plurality of objects is to capture an image including the plurality of objects, and then use an image processing algorithm to perform the salient object segmentation on the captured image.

In addition, when users capture short videos, the users select a preset addition effect, such as a sticker, in short video capturing applications, and then generate short videos. This creation method of the short videos is relatively monotonous for the users, and the users can only select a fixed addition effect to add to the short videos, and the user experience is poor.

The embodiments of the present disclosure provide a brand-new video creation method, which solves the above-mentioned problems by segmenting the salient objects in real time in images acquired by a camera, and editing the target segmentation objects in real time, and then performing short video creation for the salient objects segmented and edited in real time.

Referring to FIG. 2 , FIG. 2 is a first schematic flowchart of a video capturing method provided by an embodiment of the present disclosure. The method of this embodiment can be applied to a terminal device, and the video capturing method includes:

S201: segmenting a to-be-segmented target object to obtain a target segmentation result in response to an input event of selecting the to-be-segmented target object among a plurality of objects presented in an acquisition image of the camera.

In this embodiment, after the terminal device starts a camera, a plurality of objects are displayed in the acquisition image of the camera, and the user can select one of the plurality of objects as the to-be-segmented target object. After selecting the to-be-segmented target object, the step of segmenting the to-be-segmented target object is performed, thereby obtaining the target segmentation result.

Optionally, in order to facilitate the user to understand the operation steps of the video capturing process in this embodiment, prompt information may also be displayed on a capturing interface of the terminal device to prompt the user to input the to-be-segmented target object in the terminal device.

Referring to FIG. 3 , FIG. 3 illustrates a schematic diagram of an acquisition image of a terminal device. Exemplarily, the user opens the camera of the terminal device, and the words “aim at the object to scan, drag and copy” may appear on the acquisition image to prompt the user to input the to-be-segmented target object in the terminal device and copy the to-be-segmented target object.

S202: displaying the target segmentation result.

Specifically, the target segmentation result is displayed in the acquisition image of the camera. The target segmentation result may be displayed in a display manner different from the display manner of other objects in the acquisition image.

S203: fusing the target segmentation result, that is adjusted, with a to-be-fused video scene to generate a video in response to a triggering operation for adjusting the target segmentation result.

In this embodiment, the triggering operation for adjusting the target segmentation result includes at least one selected from a group consisting of: zooming out, zooming in, moving, and rotating. Specifically, the user can perform operations such as zooming out, zooming in, moving, and rotating by touching the screen.

Optionally, the to-be-fused video scene may be a real environment captured by the camera, and the camera here is not limited to a front camera or a rear camera.

Specifically, the fusion of the target segmentation result that is adjusted with the to-be-fused video scene may be performed by placing the target segmentation result in the real environment captured by the camera by using the simultaneous localization and mapping (SLAM) technology, which is also known as the concurrent mapping and localization (CIVIL) technology, and fusing the target segmentation result, that is adjusted, with the real environment captured by the camera.

The embodiment of the present disclosure includes the following steps: segmenting the to-be-segmented target object to obtain the target segmentation result in response to the input event of selecting the to-be-segmented target object among the plurality of objects presented in the acquisition image of the camera; displaying the target segmentation result; and fusing the target segmentation result, that is adjusted, with the to-be-fused video scene to generate the video in response to the triggering operation for adjusting the target segmentation result. The present embodiment can segment the to-be-segmented target object in real time during the video capturing process. Compared with the solution of segmenting the to-be-segmented target object offline in advance and adding the to-be-segmented target object to the short video as a sticker, the present embodiment can shorten the video capturing time and improve the timeliness of the salient object segmentation during the video capturing process. In addition, by fusing the target segmentation result, that is adjusted, with a to-be-fused video scene in response to the triggering operation for adjusting the target segmentation result, the target segmentation result can be edited in real time to realize video creation for the real-time segmented object, thus providing users with a new video creation method and improving the effect of user experience.

In an embodiment of the present disclosure, on the basis of the above-mentioned embodiment in FIG. 2 , in order to facilitate the user to select a desired matting region and improve the matting accuracy in the process of determining the to-be-segmented target object, it is detected whether the image region where the object displayed in the acquisition image is located includes a preset cursor. If the image region where the object displayed in the acquisition image is located includes the preset cursor, it is determined that the object displayed in the current image region is the to-be-segmented target object.

Optionally, the preset cursor may select a position of any region in the acquisition image as the position where the preset cursor is located.

In an optional implementation, the position of the preset cursor may be fixed, and the preset cursor may be aligned with the to-be-segmented target object by moving the terminal device. Exemplarily, the position of the preset cursor may be fixed as the center position of the display screen of the terminal device. Referring to FIG. 4 , FIG. 4 illustrates a schematic diagram of aligning the to-be-segmented target object with the preset cursor by moving the terminal device.

In another optional implementation manner, the position of the preset cursor may not be fixed, and the preset cursor may be aligned with the to-be-segmented target object by moving the position of the preset cursor. Referring to FIG. 5 , FIG. 5 illustrates a schematic diagram of aligning the preset cursor with the to-be-segmented target object by moving the position of the preset cursor. It should be understood that the cursors in the form of blocks illustrated in FIG. 3 , FIG. 4 and FIG. 5 are exemplary descriptions, and do not limit the specific display manner of the cursors.

On the basis of the embodiment illustrated in FIG. 5 , in order to avoid misrecognition, it can be determined that the object aligned with the preset cursor in the acquisition image is the to-be-segmented target object after detecting that the preset cursor is aligned with the object displayed in the acquisition image exceeding a preset time period. Optionally, the preset time period may be set to 3 seconds to 5 seconds. It should be understood that those skilled in the art may set the preset time period according to actual needs, which is not specifically limited in the present disclosure.

Specifically, detecting whether the image region where the object displayed in the acquisition image is located includes the preset cursor includes: determining a coordinate position of the preset cursor in the acquisition image; determining coordinate positions included in the image region where the object displayed in the acquisition image is located to obtain a coordinate position range; comparing the coordinate position of the preset cursor with the coordinate position range of the object displayed in the acquisition image; and determining that the object currently displayed in the acquisition image is the to-be-segmented target object if the coordinate position of the preset cursor is within the coordinate position range of the object displayed in the acquisition image.

Exemplarily, when comparing the coordinate position of the preset cursor with the coordinate position range of the object displayed in the acquisition image, the coordinate position range includes an abscissa range and an ordinate range, and the coordinate position of the preset cursor includes an abscissa and an ordinate; in this case, the above-mentioned step includes: respectively determining whether the abscissa of the preset cursor is within the abscissa range of the object displayed in the acquisition image, and determining whether the ordinate of the preset cursor is within the ordinate range of the object displayed in the acquisition image; and determining that the object currently displayed in the acquisition image is the to-be-segmented target object if the abscissa of the preset cursor is within the abscissa range of the object displayed in the acquisition image and the ordinate of the preset cursor is within the ordinate range of the object displayed in the acquisition image.

Referring to FIG. 6 , FIG. 6 is a second schematic flowchart of a video capturing method provided by an embodiment of the present disclosure. On the basis of the embodiment illustrated in FIG. 2 , S201 specifically includes:

S601: pre-segmenting the to-be-segmented target object to obtain a pre-segmentation result in response to the input event of selecting the to-be-segmented target object among the plurality of objects presented in the acquisition image of the camera.

In the present embodiment, the terminal device receives the input event of selecting the to-be-segmented target object, and the input event includes the user selecting the to-be-segmented target object. The terminal device pre-segments the to-be-segmented target object among the plurality of objects presented in the acquisition image of the camera in response to the input event. Pre-segmentation may be understood as coarse-grained segmentation, and the pre-segmentation aims to quickly segment the to-be-segmented target object. Therefore, the pre-segmentation can segment a general outline of the to-be-segmented target object.

S602: displaying the pre-segmentation result.

In the present embodiment, the pre-segmentation result may be displayed in the acquisition image of the camera, so as to facilitate the user to confirm whether the pre-segmentation result includes the to-be-segmented target object that is desired.

S603: segmenting the to-be-segmented target object to obtain the target segmentation result in response to a triggering operation performed in a display region where the pre-segmentation result is located.

In the present embodiment, the segmentation of the to-be-segmented target object may be understood as fine-grained segmentation, which aims to accurately segment the to-be-segmented target object. Therefore, the segmentation accuracy of the target segmentation result is greater than the segmentation accuracy of the pre-segmentation result.

After displaying the pre-segmentation result in step S602, the user can visually see the pre-segmentation result, so as to conveniently confirm whether the pre-segmentation result includes the to-be-segmented target object that the user desires. If the user performs a triggering operation in the display region where the pre-segmentation result is located, it means that the user confirms the pre-segmentation result, and then triggers the operation of fine-grained segmentation of the to-be-segmented target object, so as to obtain a target segmentation result with higher accuracy.

In the present embodiment, the triggering operation for confirming the pre-segmentation result may be realized by the user through touching the screen, such as clicking on the pre-segmentation result, sliding in the display region of the pre-segmentation result, etc., or may be realized by voice control, or may be realized by air gesture control.

The embodiment of the present disclosure includes: pre-segmenting the to-be-segmented target object to obtain the pre-segmentation result in response to the input event of selecting the to-be-segmented target object among the plurality of objects presented in the acquisition image of the camera; displaying the pre-segmentation result; and segmenting the to-be-segmented target object to obtain the target segmentation result in response to the triggering operation performed in the display region where the pre-segmentation result is located. Because the to-be-segmented target object is pre-segmented, the timeliness of the salient object segmentation is guaranteed. After that, the to-be-segmented target object is finely segmented to obtain a target segmentation result with a segmentation accuracy greater than the segmentation accuracy of the pre-segmentation result, which can further ensure the quality of salient object segmentation, so as to take into account both timeliness and segmentation quality.

In an embodiment of the present disclosure, on the basis of the above-mentioned embodiment in FIG. 2 , the guarantee of timeliness and segmentation quality may be achieved by different salient object segmentation algorithms.

Specifically, pre-segmenting the to-be-segmented target object to obtain the pre-segmentation result in response to the input event of selecting the to-be-segmented target object among the plurality of objects presented in the acquisition image of the camera includes: pre-segmenting the to-be-segmented target object according to a first salient object segmentation algorithm to obtain the pre-segmentation result in response to the input event of selecting the to-be-segmented target object among the plurality of objects presented in the acquisition image of the camera.

Specifically, segmenting the to-be-segmented target object to obtain the target segmentation result in response to the triggering operation performed in the display region where the pre-segmentation result is located includes: in response to the triggering operation performed in the display region where the pre-segmentation result is located, segmenting the to-be-segmented target object to obtain the target segmentation result according to a second salient object segmentation algorithm.

The segmentation speed of the first salient object segmentation algorithm is greater than a preset segmentation speed, and the segmentation accuracy of the first salient object segmentation algorithm is lower than the segmentation accuracy of the second salient object segmentation algorithm. The first salient object segmentation algorithm and the second salient object segmentation algorithm may select known salient object segmentation algorithms, and any salient object segmentation algorithm whose segmentation speed is greater than the preset segmentation speed may be used as the first salient object segmentation algorithm. The salient object segmentation algorithms, in which one salient object segmentation algorithm has a fast segmentation speed while the other salient object segmentation algorithm has a high segmentation quality, may be applied to the embodiments of the present disclosure, and the present disclosure does not limit the specific types of the first salient object segmentation algorithm and the second salient object segmentation algorithm.

Optionally, in the present embodiment, the preset segmentation speed may be determined according to an average value of the segmentation speeds that can be achieved by known salient object segmentation methods.

In another embodiment of the present disclosure, on the basis of the above-mentioned embodiment in FIG. 2 , the guarantee of timeliness and segmentation quality can also be achieved by a model obtained by training a neural network.

Referring to FIG. 7A, FIG. 7A illustrates a first schematic diagram of segmentation by a first segmentation model and a second segmentation model.

Specifically, pre-segmenting the to-be-segmented target object to obtain the pre-segmentation result in response to the input event of selecting the to-be-segmented target object among the plurality of objects presented in the acquisition image of the camera includes: pre-segmenting the to-be-segmented target object according to a first segmentation model to obtain the pre-segmentation result in response to the input event of selecting the to-be-segmented target object among the plurality of objects presented in the acquisition image of the camera. The first segmentation model is obtained by training a neural network according to a plurality of training images, each of the plurality of training image includes a plurality of objects, and the plurality of objects in the training image may be arbitrary objects.

Specifically, segmenting the to-be-segmented target object to obtain the target segmentation result in response to the triggering operation performed in the display region where the pre-segmentation result is located includes: segmenting the to-be-segmented target object to obtain the target segmentation result in response to the triggering operation performed in the display region where the pre-segmentation result is located, segmenting the to-be-segmented target object according to a second segmentation model to obtain the target segmentation result. The second segmentation model is obtained by training a neural network according to a plurality of training images, and each of the plurality of training image includes a plurality of objects.

The segmentation speed of the first segmentation model is greater than the preset segmentation speed, and the segmentation accuracy of the first segmentation model is lower than the segmentation accuracy of the second segmentation model.

In the present embodiment, the preset segmentation speed may also be determined according to the average value of the segmentation speeds that can be achieved by known salient object segmentation methods.

Optionally, in order to improve the segmentation speed of the second segmentation model, the second segmentation model may also perform secondary segmentation on the basis of the pre-segmentation result. Referring to FIG. 7B, FIG. 7B illustrates a second schematic diagram of segmentation by a first segmentation model and a second segmentation model. Specifically, the method includes: pre-segmenting the to-be-segmented target object according to the first segmentation model to obtain the pre-segmentation result in response to the input event of selecting the to-be-segmented target object among the plurality of objects presented in the acquisition image of the camera; and in response to the triggering operation performed in the display region where the pre-segmentation result is located and on the basis of the pre-segmentation result, re-segmenting the pre-segmentation result according to a second segmentation model to obtain the target segmentation result.

In an embodiment of the present disclosure, displaying the pre-segmentation result includes: outlining the pre-segmentation result; and displaying an outline of the pre-segmentation result.

Optionally, the outline may be displayed as different forms of lines, such as colored lines, dotted lines, solid lines, etc., which are not limited in the present disclosure. Referring to FIG. 8 , FIG. 8 illustrates a schematic diagram of displaying an outline of a pre-segmentation result with dotted lines.

Specifically, displaying the outline of the pre-segmentation result includes: if a portion of the to-be-segmented target object is covered by other objects other than the to-be-segmented target object, displaying an outline of a covered portion of the to-be-segmented target object in a first display state, and displaying an outline of an uncovered portion of the to-be-segmented target object in a second display state. The display attribute of the first display state is different from the display attribute of the second display state.

In the present embodiment, the display attribute includes explicit display, semi-transparent display, and transparent display. The display attribute of the first display state may be any display attribute in the display attributes, and the display attribute of the second display state may also be any display attribute in the display attributes, as long as the display attributes of the first display state and the second display state are different.

Exemplarily, the first display state may be a semi-transparent display state, and the second display state may be an explicit display state. Referring to FIG. 9 , FIG. 9 illustrates a schematic diagram of displaying an outline of a covered portion of the to-be-segmented target object by way of explicit display, and displaying an outline of an uncovered portion of the to-be-segmented target object by way of semi-transparent display.

Optionally, after detecting the outline boundary of the to-be-segmented target object and displaying the outline boundary in the form of outline, the method of the present embodiment may further include: detecting whether the outline boundary is stable; if the outline boundary is unstable, performing stability processing on the outline boundary. Whether the outline boundary is stable may be determined through phenomena such as whether the outline is flickering and jumping between a plurality of objects, and the like. In the pre-segmentation process, the pre-segmentation process is performed in real time. If the outline does not flicker and does not jump between a plurality of objects, it is considered that the outline boundary is stable. The stability processing of the outline boundary may be achieved by the segmentation time of the salient object segmentation algorithm, that is, if the outline boundary of the pre-segmentation result is unstable, the user may not confirm the pre-segmentation result, and confirm the pre-segmentation result after the outline boundary of the pre-segmentation result is stable.

In the embodiments of the present disclosure, the pre-segmentation result is outlined, and the outline of the pre-segmentation result is displayed, which can facilitate the user to confirm whether the pre-segmentation result conforms to an expected segmentation effect.

Referring to FIG. 10 , FIG. 10 is a third schematic flowchart of a video capturing method provided by an embodiment of the present disclosure. In the present embodiment, on the basis of any of the above-mentioned embodiments, S203 includes:

S1001: if the triggering operation is detected on the display region where the target segmentation result is located, detecting whether there is a plane whose distance from the camera is within a first preset distance range in a real environment within a field of view of the camera.

In the present embodiment, the plane detected is a plane for placing the target segmentation result, which can be any plane in the acquisition image, such as any plane in a space such as a wall, a surface of a table, the ground, a surface of a cabinet, and the like.

Exemplarily, if the first preset distance is 5 meters, this step is to detect a plane, whose distance from the camera is less than or equal to 5 meters within the field of view of the camera of the terminal device.

S1002: if there is a plane whose distance from the camera is within the first preset distance range in the real environment, placing the target segmentation result on the plane.

Exemplarily, within a field of view of 5 meters from the camera, if a plane that can be used to place the target segmentation result is detected, the target segmentation result is directly placed on the detected plane.

Optionally, when the target segmentation result is placed on the detected plane, the shadow of the contact surface between the target segmentation result and the detected plane may also be displayed to obtain a better display effect. How to display the shadow of the contact surface may be referred to the introduction of the prior art, and is not described in detail here.

S1003: if there is no plane whose distance from the camera is within the first preset distance range in the real environment, placing the target segmentation result in a space, and a distance between the placement position in the space and the camera being a second preset distance.

Exemplarily, if the second preset distance is 0.5 meters, this step is to directly place the target segmentation result in a space with a distance of 0.5 meters from the camera when it is detected that no plane that can be used to place the target segmentation result is within the field of view of 5 meters from the camera. There is no limit on the specific location of placement here, as long as the placement location satisfies the condition of a distance of 0.5 meters from the capturing component.

It should be understood that step S1002 and step S1003 do not limit the sequence of execution.

In an embodiment of the present disclosure, after segmenting the to-be-segmented target object to obtain the target segmentation result in response to the triggering operation performed in the display region where the pre-segmentation result is located, the method of the present embodiment further includes: if the triggering operation by a user is detected on the display region where the target segmentation result is located, determining that the user confirms the target segmentation result, and performing a step of detecting whether there is the plane whose distance from the camera is within the first preset distance range in the real environment within the field of view of the camera.

In the present embodiment, the triggering operation performed in the display region where the pre-segmentation result is located may be triggered by the user through touching the screen, or may be triggered by the user by performing an air gesture operation.

Specifically, the triggering operation by the user on the display region where the target segmentation result is located includes: an operation of releasing the target segmentation result after dragging the target segmentation result for a preset time period.

Exemplarily, if the user selects the target segmentation result in the acquisition image and drags the target segmentation result, it is deemed that the user confirms the target segmentation result and confirms that the operation of fusing the target segmentation result with a real scene captured by the camera is to be performed.

Referring to FIG. 11A, FIG. 11A illustrates a schematic diagram of the user selecting and dragging the target segmentation result in the acquisition image.

In one case of the present embodiment, if a portion of the to-be-segmented target object is covered by other objects other than the to-be-segmented target object, the user needs to drag the region corresponding to the portion of the to-be-segmented target object that is not covered by other objects, then it is deemed that the user confirms the target segmentation result and confirms that the operation of fusing the target segmentation result with the to-be-fused video scene is to be performed. It may be understood that if the user drags the to-be-segmented target object corresponding to an explicit display part, it is deemed that the user confirms the target segmentation result and confirms that the operation of fusing the target segmentation result with the to-be-fused video scene is to be performed.

Referring to FIG. 11B, FIG. 11B illustrates a schematic diagram of the user dragging the portion of the to-be-segmented target object that is not covered by other objects.

Optionally, in the process of dragging the target segmentation result, the user may further perform operations such as rotating, zooming, moving, and the like on the target segmentation result to adjust the placement angle of the target segmentation result, and the placement angle is adjusted to a target angle that is compatible with a detected plane angle, and after the user releases the finger, the target segmentation result after adjusted is placed on the detected plane.

In the embodiment of the present disclosure, by the operation of releasing the target segmentation result after dragging the target segmentation result for the preset time period, it is deemed that the user confirms the target segmentation result, and the operation of fusing the target segmentation result with the to-be-fused video scene starts to be performed. In this case, the steps of the user confirming the target segmentation result and placing the target segmentation result in the real environment acquired by the camera are completed in one operation step, which can simplify the user operation, shorten the overall time of the video capturing process, achieve the effect of improving the efficiency of video capturing and user operation, and thus improve the user experience.

In one embodiment of the present disclosure, before segmenting the to-be-segmented target object to obtain the target segmentation result in response to the input event of selecting the to-be-segmented target object among the plurality of objects presented in the acquisition image of the camera, the method of the present embodiment further includes: acquiring images during a segmentation process of the to-be-segmented target object in response to a triggering operation of a capturing function. The images include a real environment captured by the camera. Correspondingly, fusing the target segmentation result, that is adjusted, with the to-be-fused video scene to generate the video in response to the triggering operation for adjusting the target segmentation result includes: generating the video according to the images during the segmentation process of the to-be-segmented target object.

In the present embodiment, the triggering operation of the capturing function may be understood as triggering the capturing function after the terminal device starts the camera to enter the acquisition image, then the camera may capture the whole segmentation process and the process of the user adjusting the target segmentation result and fusing the target segmentation result after adjusted with the to-be-fused video scene, and generate a video. For example, continuing to refer to FIG. 9 , in the state of the rear camera, the objects acquired by the camera include a cat and a person. If the person is the to-be-segmented target object, the whole process of segmentation and adjustment of the person is captured and a video is generated.

In the present embodiment, the triggering operation of the capturing function of the terminal device may be a touch operation on a capturing button in the acquisition image (such as a circular icon below the acquisition image in FIG. 3 , FIG. 4 , FIG. 5 , FIG. 8 , FIG. 9 , FIG. 11A, and FIG. 11B).

Specifically, the user may trigger the capturing function of the terminal device by clicking the capturing button in the acquisition image, or the user may trigger the capturing function of the terminal device through voice control, or the user may trigger the capturing function of the terminal device through an air gesture operation.

In another embodiment of the present disclosure, fusing the target segmentation result, that is adjusted, with the real environment captured by the camera to generate the video in response to the triggering operation for adjusting the target segmentation result includes: generating the video according to the target segmentation result that is adjusted and the to-be-fused video scene in response to a triggering operation of a capturing function and the triggering operation for adjusting the target segmentation result.
